PETROLEUM-GAS GENERATOR AND BURNER FOR HEATING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 498,410, dated May 30, 1893. I Application filed April 5, 1892- Serial No. 427,784.' (No model.)

To all whom it may concern.-

Be it known that I, THOMAS ALLEN SToMBs, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and and useful Improvements in Petroleum-Gas Generators and Burners for Heating Purposes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention has special reference to that class of gas stoves in which the gas consumed is generated by the flame or heatof the stove. Heretofore stoves of this class have been constructed with a supply pipe leading into a generating retort and a pipe for conducting the gas from the retort to the burner, the flame from which generates the gas.

Among the disadvantages of stoves constructed in this manner are, first, the formation and deposit of carbon in the supply pipe and retort; and, second, the incomplete combustion of gas.

These disadvantages my invention aims to overcome and to this end it consists of certain novel features and combinations of parts which will hereinafter appear and be pointed out in the claims.

A further object is to produce a more simple, cheap, and handy device than has heretofore been known.

Referring to the accompanying drawings which illustrate an apparatus embodying the essential features of my invention Figure 1 represents alongitudinal section thereof; Fig. 2, a detail showing more clearly the arrangement in the feed pipe.

The reference letter or represents the framework of the stove which is of the usual construction. Directly under the top of the frame is located the horizontal retort A which is supplied with oil by the supply pipe B under a pressure of about ten feet of altitude, the supply being regulated by the valve G.

e which serves to deflect the flamearound its bottom. The supply pipe B enters the retort at or near its bottom and has secured in it a rod f which leaves a space between it and the interior of the pipe. Around that portion of the pipe B in which the rodfis located is fitted a larger pipe H which serves to protect the oil from the heat. Located near the top of the retort is the pipe E which conveys the gas to the burner. This pipe extends down under the retort to the burner h, and its horizontal portion is squared as seen in the drawings. The end of this pipe is closed with the exception of a short arm j which forms the burner. A stop cockiis located in the lower elbow of pipe E by which air may be admitted into the pipe. Rigidly secured to the end of the pipe E is a short standard or lug k to which is hinged the perforated tube F by means of the arm F. This tube serves to enlarge the size of the flame as will be more fully explained hereinafter. As the oil passes into the retort by way of the supply pipe the discharge pipe conducts it to the burner where it is consumed. Theheat of the burning oil acting on the exterior of the retort generatesgas therein which in a short time takes the place of the oil in the burner. This is the principle of all vapor stoves and needs-n0 further description. As'the oil is forced past the rod f it is divided into an extremely fine stream and emptied into the lower portion of the retort, where it is immediately exposed to the heat of the generating flame on the exterior of the retort. By this arrangement the formation and deposit of carbon in the supply pipe is prevented, because the oil is kept cool and no gas is allowed to generate in the supply pipe. By reason of the large size of the retort and the intense heat applied to it the carbon that is formed therein is readily consumed. When it is desired to increase the size of the flame given by the burner the perforated tube F may be swung over it and the gas and air will be carried up to the bottom of the retort before it is consumed.

It is evident that the construction herein shown may be varied or modified by a skilled mechanic without departing from the spirit and scope of my invention, hence I do not propose to limit myself to the precise construction herein shown, but consider myself entitled to all such variations.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a gas stove, the combination with a cylindrical retort, of supply and discharge pipes connected thereto at its bottom and top respectively, a burner attached to the end of the discharge pipe, an air cock or valve by which the gas is supplied with air for mixing purposes, and a perforated hood or tube pivoted near the burner and capable-of being swung-back and forth on its pivot so that it will cover or uncover the burner, all'substantially as described.

2. In a gas stove, the combination of a retort, a supply pipe leading thereto and emptying therein at or near its bottom, a central core located in the supply pipe and having a presence of two witnesses.
